The present research was aim to examine whether the relationship between work engagement and objective task performance is moderated by perceived organizational support (POS). Based on the existing literature, perceived organizational support is hypothesized to strengthen the positive association between employees' work engagement and their objective task performance. The hypotheses were tested on a sample of 1049 employees. Results of hierarchical regression analysis show that (1) work engagement is positively related to objective task performance, and (2) the relationship between work engagement and objective task performance is moderated by POS, such that the positive relationship is more significant when POS higher than lower. In the end, theoretical and practical implications, and suggestions for future research are discussed.
